WILLIAM; C. GILMORE, OF: WACQMTEXAS;

GAS GENERATOR.

Application led November 7, 1924.

To all /1 0h om it may conce r11,

Be it known that I, VILLI'AM C. GILMonn, a citizen oi the United States,residing at lVaco, in the county ot' McLennan and State of Texas, haveinvented new. and useful linprovementsiu Gas Generators, of which the.

following is specilication.`

This invention relates to an improved generator for acetylene gas, theGeneralobject ofthe. invention being to provide automatic means forcontrollingT the feeding of the carbide by the n'iovemeut ofthe gasbell.

Another object of the invention is toprovide balanced spring means forholding the Afeeding valve for the carbide upon itshseat,

and also to provide a bridge for keeping the weight of the carbide otfthe valve.

A further object of the invention isto provide protective kcasings forthe spring means and the valve stems to prevent any thing frominterfering with the operation ot' the valve.

A still Vfurther object isto make the valve of such aform as toinsureits proper closing and also to'provide aI protective hood for the inletend of the gas pipe.

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described, illustrated in the accompanying drawingsand specifically pointed out in the appended claims.

In describing my invention in detail, reterence will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in whch:-

Figure 1 is an elevation of the invention.

Figure 2 is a longitudinal sectional view thereof.

Figure 3 .is a plan view.

Figure 4 is an enlarged sectional view showing the means for controllingthe feed of carbide.

Figure 5 is a section on line 5-5 of Figure 4.

Figure (l is a section on line 6-6 of Figure 4.

In these views 1 indicates the base of the device which is to containthe water for the generation of the gas and 2 indicates the reducedextension which is connected with part 1 by the flaring central part 3.A part 4, surrounds the part 2 and has its lower end secured to thecentral part 3, the walls of Serial N'o. 748,460.

partsand 4* forming a' waterl chamber 5 which acts as a seal'for thelielld, this' bell enclosing the upper portion of' part 2; Ig prefer tomake these parts of'lexagon sha Je, as showninthe drawings,sothatithepipe connections may rbe 'easily made on flat'sides. Thehopper 7, also of hexagon shape, is suspended inthe upper'portion ofpart- 2 by means of the hook sl'iape'dbrackets 8, Said hopper having atapered bottom with an v opening 9 tlierein,.the vend'wa'll's oftheopening being `ot' invertediV-sha'pe. An inverted V-shaped platelyextendsacross the-lower' part of the hopp-erabove the opening, as'

shown. This openingis closed'by the valve- 'lllwliich is alsootimf'erted'V-shape in crossv section so as to tightly close theopening;this valve beingcarried the U-shaped'rod 12, the limbs otwhichextendftliroughtlie vertically arranged tubes 13 passing throughthe hopper andthe bight'otsaidVU-shaped rod carrying the valve. Theupper endsof said rod extendJ above the hopper andthe tubes .13"sothat'they will'fbeengagediby the bell whenthe-san'ie is in itsy lowerposition'. A: pair of tubes l'isr locatedin the' hopper, the upper endsof said tubes being closed while the lower ends are open. Coil springs15 are arranged in said tubes and these spril'igs are connected with thebightof rod 12 and their upper ends are secured to eye bolts 16 whichengage nuts 17 on the tops of the tubes 14. By means of these nuts andeye bolts the tension of the springs may be adjusted. kThese springswill hold the valve 11 upon its seat but the weight of the bell 2 uponthe ends of said rod 12 will push the rod and the valve downwardlyagainst the action of the springs so as to move the valve cti' its seatand permit some of the carbide to drop through opening 9 into the waterin the base and thus generate gas which will rise in part 2 and into thebell thus raising said bell `and permitting the springs to Seat thevalve 11 and thus cut off the supply of carbide. The plate l() willprevent the weight of the carbide in the hopper from interfering withthe working of the valve and the tubes enclosing the limbs of rod 12 andthe springs will prevent carbide or anything else .from interfering withthe proper working of these parts.

The gas pipe 18 passesthrough one side of part 1 and a cylindrical pipe19 is con-
